These 'inova-ble aws are preferably spring pressed for movement away from the i stationary 1 aws, as fb y meansof a springi28. 1 Jawactuatingflevers 29-30"are employed toelosthejaws and to release thenr' for Y opening;-1novement, the

ation and the lever 30 being-operatively con-. *nected' withthe'dever 29,;as-by meansof a link 32 whereby the two pairs of chuck jaws are operated simultaneously, one set being opened whenthe'other set .is being closed, the ends of thedever's'Q9 3Obeing preferwe 3,to*accon1plishthis result, :in which "the fbase, and-chuck mechanism is moun ted ably formed-to cam shape,-as shown'in Figfigure the pair o fj'aws at} the left are in'ftheir open position, and "those at the right are closed, the handle "31 being swung to the right torevei"se-tlie-posi ionof said aws.

th (than {I Ytheol rationoftwist'ing thebrushmaterirl w es "33 are eommo'i'ily"employed,

distrib uted in a layer between such wires, and the latter are caused to be grasped by the chuck jaws at certain points, and as shown in Figure 1 of the drawings, in which the inner ends of the aws at the right and the pair of jaws nearest the lengthwise center of the machine, and at the left thereof, are shown as grasping the wires. The machine being now operated to twist the wires, as shown in Figure 7, such wires are consequently shortened, and the mechanism comprised in this invention is constructed to permit this short ening of the wires and to permit the chuck jaws to be opened without changing their position with respect to the wires, and by a single movement of the chuck actuating levers.

This mechanism comprises a stop se cured to the bed 10 and adapted to temporarily locate the base 21 in an advanced position and thereby temporarily prevent its backward movementv to they position shown in Figures 1 and3 of the drawings, in this advanced position the back edge 01 said base resting aga-inst said stop that also operates in connection with a striker 86 secured to a controller 37 pivotally attached to a block and releasing latch pivotally secured thereto at its outer end, the nose 89 of such latch being adapted to make contact with a releasing plate l-l'sccured to the edge of the bed 10, and an edgeof said nose also being adapted to make contact with a resetting plated-2 also secured to the edge of the bed 10, and as shown in Figure 4- of the drawings. A

-rctainer is secured to and projects up- 'ardly JillOlll the base 2i, in position to receive the heel all) of the holding and releasing latch, which heel is adapted to project across and rest upon the upper end of said retainer to hold said latch in its uppermost or raised pmsition, and as shown in Figures 5 and 9 of the drawings. 7 i

in the operation of the device, the parts being ill the. position shown in F gure 1,

with the gripping aws holding the wires 33 at points adjacent to the material 321-, the

spindle l5 t in motion and thctwisting ol? the wires takes place. As. thistwistmg prg s the wires are shortened, causing il 1 21 to be moved toward the lengthwise center oi the machine, during which movement the striker passes along the top of the stop until the parts reach the po- 1 sition shown in Figure 7 of the drawings,

when the machine is stopped tion or the first stage of the ation. in this posit-1011 of at the completwisting open the parts the striker86 has been drawn to a point a slight distance beyond the stop 85 and the ends of the twisted wires at the right hand end of the twisted structure project beyond the right hand end of the chuck jaws in the chuck 17 and into a socket or stop piece $4 at the end of the spindle 15, and shown in Figure 1 of the drawings, in which position such wires were placed when the brush structure was first clamped in posi-.

tion, the wires at the opposite end of the structure being originally placed in their proper positions. 7

The chuck at either end of the i'uachinc is new opera ed to release the wires, or both chucks may be so operated, and the pull oi the weight 22 will seat the striker 36 squarely aga', 1st thestop 35, and as shown in F igure 8 oi. the drawings. The chucks are now operated to grip the wires near their opposite ends, the lever 29 being swung from the position shown in Figure 7 to the position shown in Figure 8, thus releasing the wiresirom the grip of the jaws 252'( and causing them to be gripped by the jaws 24-. 26, and as shown in said Figure8. The spindle 15 is new again put in operation and the extreme ends of the wires are twisted, during which operation the structure is again shortened, drawing the base 21 to the position shown in Figure 9, in which position the strike 36 separated a considerable distance from the stop 35. In this movement of the base 21 the nose 39 of the holding and releasing latch has engaged with the edge of the releasing plate +21 that acts to raise this end of the controller 37 until the heel 410 of said latch is above the upper .end of the retainer 4.3, when, said latch be,

ing spring actuated in one direction, as by a, spring as, its heel a0 is swung over the upper edge of the retainer and the controller is thereby held in its raised position, the striker 36 in this position being higher than i the top edge of the stop 35.

The chuck jaws being now released for ren'ioval oi the twisted structure the weight 22- draws the base 21 to its rear wardiuost position, and as shown in Figure 1 ol the drawings in this movement the striker 36 pass ing over the stop'35. As the base 21 reaches the limit of its backward movement the nose 39 of the holding and releasing latch strikes the resetting plate 42, swinging said latch on its piyot to the position shown in Figure 1,

thereby permitting the controller 37 to fall, as, by gravity, and lower thcslriker 363111) contact withthe stop 3 and also lower the latch behind the retainer 4.3, the latter now operating to hold the latch in this position, the parts being now in position fol-another twisting operation. I
